google.com shows hits at several web sites: www.testcompany.com, www.sswug.org, www.sql.ru, www.obssa.com, and www.five24.com.
testcompany.com deals with spam issues - it would appear a sql newsletter was being sent unsolicited.
sql.ru has notification of Kalpesh's activities as material has been posted.
obssa.com doesn't count.
five24.com looks to have been SQL-based at one time (including articles contributed by "Kalpesh Thaker") but now looks to be personal
www.sswug.org, however, has several postings from the great author Kalpesh Thaker. I felt it best they be aware someone by the same name was having submittal problems and provided the necessary links to let him decided for himself.
Mr. Thaker shows no activity in usenet.
As I admitted to asswug.org, there could be more than one, just as Bob Smith in the US is a popular name, but for two of them to be frequenting SQL like a salt lick in the woods has to be a but unusual.
Mr. Thaker seems to have severely underestimated the size of the planet in Earth terms. Providing, of course, someone didn't supply his material so he would be blamed the plagiarist.
15-20 years ago, when some of us were online, we saw the world to be fairly small, even by Internet standards. And that was before most of the people who read this were online. Now, the planet has shrunk to almost nothing. A marble. A bb.
